The slightly brown coloured whippij that is often acquired after strenuous physical activity or a stressful experience. One would be particularly susceptible to bum gravy if it was an extremely hot day.

Friends: "No, why?"
Jeremy: "I can feel the bum gravy brewing again"

when practicing anal sex, sometime you may notice a thin sludgy brown liquid on your penis. this is known as bum gravy.
i took home this girl the other night, we had normal sex, then decided to try anal. about five minutes later my penis was covered in bum gravy. not a pretty sight!!!
